Site working as per requirements for Sub02. 

For carousel: uses fetch to get the content from images_and_labels.html, 
then inserts into the main page. Each item is tagged as a carousel item 
which the script identifies. Hides all the items, then cycles through showing 
one, hiding it and showing the next one every 3 seconds.

For daily random quotation: get_quote pulls quotes from the quote json, picks 
a random one, adds in the extra text formatting, and saves it to quote_today.txt
with the date. Checks txt file every time to see if dates match, if they do it 
returns quote to banner script, where its injected to html. If no, new quote 
made and overwritten to text file.
